My phone asks for a my email password but then it won't let me enter it

I managed to solve the issue, although I'm not exactly sure how. I went to the Xfinity store and two reps worked on it for the better part of an hour. Turns out, Xfinity sent out an email that directed users to change their password. This was in response to a hacking of the company last year, or perhaps the prior year. I have read that if you have a strong password, there is no need to change them. Anyway, I put the remail aside with no action. Turns out, that was the issue. The agent at the store was doing things so fast, I'm not sure exactly what he did. But we ended up resetting my account and putting in a new password. My phone then started to download the emails, and I had to log in with a new password, via the Xfinity account, and my laptop also downloaded the emails. The Xfinity agents were great in working to resolve this, as it wasn't easy, and I could see their frustration.
